That's a great question! A lot of people have these special Bicentennial half dollars with the "1776-1976" date and wonder the same thing. The short answer is: yes, they can be worth more than 50 cents, but most of them aren't. It really comes down to the specific type of coin you have.
The vast majority of Bicentennial half dollars you'd find in pocket change are made of a copper-nickel alloy. Over 500 million of these were minted, so they are very common and, in circulated condition, are typically only worth their face value of 50 cents. If you have one that's in pristine, uncirculated condition, it might be worth a couple of dollars to a collector.
The real value comes from the special collector versions that were made with silver. The U.S. Mint issued sets for collectors that contained Bicentennial half dollars made of 40% silver. Because of their silver content, these coins will always be worth more than face value, with their base value tied to the current price of silver. These special silver coins were sold in both uncirculated and "proof" versions, the latter having a beautiful, mirror-like finish.
So, to figure out if your coin is valuable, the key is to determine if it's a common copper-nickel coin or one of the less common 40% silver versions. The coin's condition also plays a huge role; a perfectly preserved coin is always worth more than a worn one.
